Hole in hose under engine cover HELP!!

[EDG08]

So I took the engine cover off to clean the engine and found a hoel in a hose twords the back of the engine. It is about the size of my finger, I can tell it is sucking air because when I plug it a whistling noise goes away. No check engine light. Anyone have any idea what the hose is for? I have an appt next week to change belts and am wondering if I can wait that long? Thanks guys
Attached are a few pictures for soem reference.

This is common, the hose with the hole goes to the oil separator,and the hose that connects the valve covers will get worse if not replaced. And there is a third hose that is under the oil separator , this one is about six inches long. You should replace all three. If not replaced they will lean out your fuel mixture, thus gas mileage out the window and generate fault codes "Bank1 and Bank2 too lean"....or MAS fault
For some reason these hoses can`t take the heat and oil, they get all gummy and collaspe or rip apart. They are not expensive, but the short hose, Hummm is a bear to change, the Fire wall must be lifted to get to it. And if you notice a hint of blue smoke at the exhaust, replacing the oil separator would be a good idea.
Hope this helps..

Hey Negritoamni!!!
you dan'm right! this is very common issue to these hoses area to get messed-up. I've been having the same lean issue to on the same car 4.4 M62 engine, but everytime I checked these hoses they all appear to be in great shape, like they may have been replaced not too long ago by the previous owner.
But today, I was decided to inspect a little bit farther: Meaning I checked the two that comes from the oil separator to the other end. And that's when I finally discovered a( line cut-off ) under the clamps from one of these hoses.
Well once I did not have a new hose to replace, I just removed the top hose where the clamp were sitting by cutting a little bit of and push the hose back where it belong. Well, service engine light usually come back every: 3 to 6 miles but I drove nearly 10 miles now and I haven't seen anything yet! so far, so good!!!

Glad to see, it helped you...I have used alot of the info in the forum myself which has saved me time and money

Thanks, your right the hose is really soft and feels gummy. Is this a do it yourself project or stealership? From the looks of it there is not much space to work back there!!

the two top hoses you can replace in 20 mins...
The one short one a couple of hours. But yes you should be able to replace them yourself....
a little motivation....$1200 dollars at the dealer with the oil separator replacement...I don`t think so....

I had a thought. How about I yank this entire system out, and throw it in the woods!?

I will plug up the holes in the intake and let the crankcase breather/vent just vent to atmosphere. Have you heard of this? Do you think too much oil will come out of the breather/vent and make a mess?

WOW, this must be common! I just fixed mine. I started this thread.
